摘要
针对煤层顶板石灰岩瓦斯这种特殊的瓦斯赋存方式,山西义棠煤业公司采用"分源抽采、边抽边采和加强上隅角抽采与通风"的瓦斯综合治理模式,通过对工作面前200 m范围进行瓦斯抽放,使工作面顶板内瓦斯压力保持在安全值内,解决了回采工作面瓦斯超限造成的安全隐患,对其他类似地质条件和瓦斯赋存的矿井有一定的指导和借鉴。
Based on special gas occurrence manner of coat seam roof limestone, comprehensive gas treatment of split source,draining while mining and strengthening corner drainage and ventililation was adopted in Shanxi Yitang Coal IndustryCorporation. Through gas drainage in 200m ahead of working face, gas pressure under face roof was controlled in safetyvalue, which solved potential safety hazard caused by transfinite gas in stope face and provided guidance and reference tocoal mine gas occurence in similar geological conditions.
